CASEMENT WINDOW.

:Application filed February 23,` 1927. Serial No. 170,102.

This invention relates to improvements in easement windows and has particular reference to improvements in the hinges for such windows. The invention is particularly applicable to metal easement windows.

One object of the invention is to provide a hinge for a metal easement window which shall function and appear as an ordinary hinge, but which permits the window to be moved into a given position to permit cleaning oi both sides of the window from the inside of the room. provide a hinge including certain novel features of adjustment. A further object of the invention is to embody the features as aforesaid in a hinge which does not require special arrangements 'for crating and shipping. Other objects will appear as this specification proceeds.

In the manufact-ure of metal easement windows there is necessarily a plus and minus factor in the lit of the window sash against the frame. That is to say, when the window is closed, it will be found that the edge of the sash nearest the hinges, rarely, if ever, fits tight against the frame for the entire length or' the window. This occurs because of an inherent tendency in the metal to spring or get out of alinement. It is also due to handling and shipping. The industry recognizes this objectionable fault, and it has been proposed to eliminate the same, either' by individual fitting of the window on the spot, or by providing means, such as an eccentric bushing within the hinge pivot, for adjusting the hinged edge of the window so as to obtain a tight fit.

Individual adjustment or iitting of each window is impraeticable ttor obvious economic reasons, besides being unreliable. Adjustment by means of a turnable bushing is found only in connection with offset hinges and for that reason is objectionable.

This invention provides a hinge which is mounted close to the window, thus permitting shipping in bundles, obviously an economic factor of importance. Second, this invention provides a hinge permitting the window to be moved into off-set position without using an oit-set hinge. Third, means are provided for adjusting the fit of the window, and fourth, securing and releasing means are provided to permit the operation of olif-setting the window.

The means provided are such that they fall within the scope of the ordinary manu- Another object is tofacture of metal easement window, are simple and elective in operation and not expensive. n n

The invention is illustrated in its preferred form in the accompanying drawings in which Fig. l is a view of a easement window and frame showing the hinge side thereof and with parts broken away.

Fig. 2 is a view looking from the left in Figure l with the window open, the frame in section and parts broken away. This view is also in the direction ot' arrow 2 in Figure 3.

Fig. 3 is a. detail perspective View showing the adjusting and locking means.

Fig. 5 is a sectional view on line 5 5 in` Figure 2, but shows the window closed.

Fig. G is a plan view similar to Fig. 4 but shows the window in open od-set position.

Fig. '7 is a perspective view of a part of the hinge.

All frames and sashes of modern metal easement windows are lmade of Z-bars. In the drawings the numeral denotes the :trame and the outer flange is marked 11. The window sash Z-bar is marked 12 and its outer flange 13. The member or angle piece marked 14 in Figures Ll, 5 and 6 represents the usual j amb angle for mounting the window in masonry or concrete.

The window is provided with an upper and a lower hinge. As the construction is alike, only one will be described, though certain parts are reversed in the two hinges. The hinge is a double hinge, that is it permits the window to open and to be swung in open position into an oH-set position. Each hinge consists of a relatively fixed hinge plate and a relatively movable hingeplate which are bored -so as to be united and pivoted on a hinge pin.

Referring first to Figure 7, the reference numeral 15 'denotes the fixed hinge plate havholes 16 for attachment to the vertical frame Z-bar 10 by means of bolts 17, see Figures 4, 5 and 2. The bolts also pass through the jamb angle 14. when such is used. The fixed hinge plate may also be provided with a wing 18 which passes through the flange 11 and lies in over the horizontal frame bar 10 and is screwed fast with a screw 19. At the bottom of Figures 1 and 2 t-he wing 18 appears attache'd to the lower horizontal frame 10. The plate 15 is bored as at 20 to receive the hinge pin 21.

The movable hinge plate is in the form of a long hinge leaf 23 having two pivot lugs 2t, Q4: bored to receive the hinge pin 2l and fitted into the fixed hinge plate l5. The other end of the plate is hinged at Q5 to a hinge lug QG secured to the window. It will therefore be seen, that the window may be swung open on the hinge pin 2l and thereafter the window may be swung away from the plate 23, turning on the hinge Q5, and be moved into oft-set position shown in Figure C. rl`his type ot hinge is known to the art..

In order to adjust the window to fit tight along the hinge edge, means are provided at the corners tor forcing them against the window i'rame. In this instance there is provided both at the top and at the bottom an adjusting Screw 27 which is screwed into the outer flange 123 ot' the window bar l2 and which screw bears against the inside of the movable hinge plate Q3 as best seen in Figure 5.

llfhen the window is closed, it is secured by means ot a catch at the frce edge in the usual manner and therefore not shown. in the closed position, therefore, the hinge edge 28 oi the window, may bc torced tight against the outer flange ll of the frame lt) by screwing the adjusting screw 2T outward against the hinge plate 23. Such adjustment made at the installation will be permanent and the window will close tight.

During the normal operation ot the window, it is obvious that some means must be provided to secure the window to the hinge plate and whereby the parts and 2o will operate as one piece. `ruch securing means must also be arranged so that they may be released to permit swinging the window on the hinge 25. As best seen in Figure t3, the hinge plate 23 carries an inwardly projecting lug El() having a slot 3l. The lug 3() is adapted to enter a slot 32 in the window bar fiange 13 and project thereto to the inside thereof.

'lhe numeral Si denotes a securing catch mounted to slide on a screw 35. The edge 3U ot the catch slides against the inside ot the window bar flange 13. The latch has a bevelled nose 3T adapted to enter the slot 3l in the lng 80, and a finger piece 38. Normally the latch engages the lug 30, the nose 3T passingl through the slot 3l therein, and the window and movable hinge plate Q3 are firmly secured togetlier. lVhen it is desired to clean the window or for other r xasons, the latch is pulled out ot' the lug 3U by tapping lightly on the nose piece, and the window and hinge plate being thus disconnected, the window may be swung on hinge 25 into the otl'set position shown in Figure (5.

At the bottom of the window, see Fig. Q, the construction the saine as at the top but certain parts necessarily reversed.

From the foregoing it will be clear that this invention provides a easement window hinge which projects very little, and the windows may therl'ore be shipped without special provision to protect a projecting ofi-set hinge.

Again, means arc provided i'or positivelyr securing the window to the hinge, yet; it may be quickly released and moved into oflsct position. lt will also be observed that the securing or releasing ol the window does 'not disturb the adjustment made with respect to tight fit. The construction also provides a hinge and window having all the advantages ot oft-setting, yet when the window is operated normally and opened, there is only the usual small opening between the hinge edge 2b and the window frame, see Fig. 2. lVhcreas with oil-set windows there is always a very large opening at this point, permittingr objtwtionable passage of wind and rain.

l claim A hinge for metal easement windows conipi'ising in combination a fixed hinge plate. adapted to be secured to a vertical portion of the window frame, said plate having an integral lateral extension plate adapted to be cured to a horizontal portion ol' the window trame, a hinge lug?r adapted to be secured to the window, a movable hinge plate pivoted to and between said fixed hinge plate and lug. a slotted lug on the movable hinge plate adapt ed to enter through a slot in the window web and project on the inside thereof. a f-lide mounted on the sash and adapted to engage the slot` in the movable hinge plato to sccare. the latter and the window together. and a screw in the window sash accessible from the inside when the window is opened for adjusting the sash relative to said movable hinge plate.
